How about bass tube amp

i'd also like to point out the baga: 12x kt90s, 4x el84, 1x 6n1p, 100lbs, 500w. 9 years later on the same kt90s!

Giving it a higher plate load is not a problem. Besides, there are other 813 projects on the web, which give me the idea in the first place. I'll start with a plate voltage of 1.4 KV, and just take it from there.

In short, putting one in a tube amp is like putting a weed whacker engine in your lovingly restored '49 Harley-Davidson. And, they give 2kV AC, not 1.

Ok, best used for Tesla Coils!
Strange that you used the motorcycle analogy.
A weed whacker engine in a Charley Davidson might make it go better, but it would still handle like a pig.
Sorry, I have only ever owned classic Triumphs and the only Harley I would have ever liked to own was a 1942 750 side valve.
